HIRAM VAN PELT, OF BATH, NEW YORK.

ROAD-SCRAJPER.

Specification of Letters Patent No. 17,529, dated June 9, 1857.

To all whom it may concern:

Be it. known that I, Hilmar VAN PELT, of Bath,in the county of Steuben,in the State of New York, have invented a new and Improved Scraper forScraping Earth; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereo-n.

My improved scraper is so constructed, that it is, at. all times, in theproper position for performing its functions, viz: right side up andright end foremost. It is made with scoops on each of its ends inreverse or alternate positions, which enables it to always present oneor the other of its ends for scraping or scooping up the earth. By thisarrangement., most of the labor of handling the scraper is avoided, anda considerable saving of time is effected; which would otherwise beexpended in turning the scraper back again into a perpendicularposition, or at an angle of about forty-five degrees, for refilling` andin changing the position of the t-ean My arrangement also allows theteam to be attached to the scraper by a much shorter chain than isusually employed with the older inventions for scraping, &c., and ofobtaining a draft better suited to the propelling power.

By reference to the accompanying drawingit will be seen that I employiron rods C, C, on each side of `the scraper, for the purpose ofattaching the chain E, E, thereto. The said chain is fastened to aloosely sliding ring, which allows it (the chain) to be transferred, onthe rods C, C, from one end of the scraper to the other, wit-hout beingdetached therefrom. This arrangement is not only important, but `veryconvenient, as will readily be. observed.

After the scoop I, of the scraper, has been filled with the earth, thesaid scraper is then thrown over, which deposits its contents on theground. The team is then changed to the rear end, which changes the saidrear end to a front end, the scoop of which is ready for excavating asin the former instance. The scoop on said end is then filled andemptied, and vice-versa.

The chain, when the team changes from one end of the scraper to another,does not require to be disconnected, but slides backward, and forward,as the case may be, to its proper position. In this manner, also, Iobtain an alternate change of draft, as will readily be perceived.

To enable others skilled in the art to make and use my invention I willproceed to 'describe its construction and operation.

Iconstruct the sides of my scraper as seen at A, A, in the accompanyingdrawing, of wood or iro-n so shaped at the ends as to receive the pointsor edges which are shown at B, B, which points or edges are to be madeof cast or wrought iron or steel. C, C, are the rods on which the chainsslide by which a change of draftis obtained from end to end alternately.Handles D, D, for lifting the scraper, as shown in the drawing, areformed on each end of the rods C, C, on which the chains slide, and areextended beyond the`point to which the chainsI can slide; and in aA fullsized scraper will be about nine inches long.

E, E, are the chains to which the team is attached to the scraper, whenin operation.

F, F, is the spreader to be made of wood or iron which keeps the chainsapart and separate so as to give the scraper a fair chance to revolvewithout being entangled inthe chains. Swivels -1nay be formed in thechains to prevent them from becoming twisted. A partition H, separatesthe scoops from each other, as shown in the drawing.

I am aware that a scraper has been made to revolve upon pivots, placedwithin a suitable frame, and therefore I do not claim such as myinvention; but

That I do claim as new and desire to se p HIB-AM VAN PELT. litnesses J.H. VAN I-IoUsEN, E. L. CHURCH..
